Bumi super
Bumi super adolah planet lua surya jo massa lebiah gadang dari Bumi, tapi jauah di bawah raksasa es Tata Surya ajak Uranus dan Neptunus, nan masiang-masiang punyo 14,5 dan 17 kali massa Bumi.[1] Istilah "Bumi super" hanyo mangacu pado massa gadangnyo planet, dan indak tasirek apo pun tantang kondisi parmukoan atau kelaikhunian. Istilah alternatif "katai gas" mungkin labiah akurat untuak inyo nan barado di ujuang skala massa nan labiah tinggi, bilo " Neptunus mini" iyolah istilah nan labiah umum.
Definisi
[suntiang | suntiang sumber]Sacaro umum, Bumi super ditantuan dek massanyo, dan istilah iko indak manjalehan suhu, komposisi, sifaik orbit, kalaikhunian, atau lingkuangan alam. Samantaro babarapo sumber umumnyo satuju jo bateh atas iyolah 10 kali massa Bumi[1][2][3] (~69% dari massa Uranus, nan marupoan planet raksasa Tata Surya jo massa taketek) dan batas bawah bavariasi dari 1 [1] atau 1,9 [3] hinggo 5 kali massa Bumi[2] baikuti dek babagai definisi lain nan tabik di media populer.[4][5][6] Istilah "Bumi super" paguno juo dek para astronom untuak marujuak pado planet nan labiah gadang dari planet sarupo Bumi (dari 0,8 hinggo 1,2 kali jari-jari Bumi), tapi labiah ketek dari Neptunus mini (dari 2 hinggo 4 kali jari-jari Bumi).[7][8] Definisi iko dibuek dek operator teleskop lua angkaso Kepler.[9] Babarapo panulis labiah lanjuik manyarankan dek istilah Bumi super mungkin tabateh pado planet babatu tanpa atmosfer nan signifikan, atau planet nan indak hanyo punyo atmosfer tapi jua punyo parmukoan padek atau lautan jo bateh nan tajam antaro caiaran dan atmosfer, nan indak dipunyo dek kaampek planet raksasa Tata Surya.[10] Planet di ateh 10 kali massa Bumi disabuik planet padat masif,[11] mega-Bumi,[12][13] atau planet raksasa gas,[14] tagantuang pado apakah inyo tadiri ateh sabagian gadang batu dan es atau sabagian gadang gas.
